China Construction machinery information

Guide: a year after the subway was built, some large machinery that had never been seen in the past suddenly changed in the vision of Kunming people. What are their names? What are your skills? To this end, this newspaper inquired into the housekeeping skills of these tough guys, and gave them a nickname of "big gold in subway construction"

a year after the subway was built, some large machinery that had never been seen before suddenly appeared in the vision of Kunming people. What are their names? What are your skills? For this reason, this newspaper inquired into the "housekeeping skills" of these tough guys and gave them a nickname - "big King Kong" in subway construction. Today, let's give a show to citizens who are interested in machinery and technology

grooving machine

1 grooving machine:

King Kong who loves "soft rice"

roughness: four star

energy level: three star

grooving machine, also known as slotting machine, is the mechanical equipment for excavating grooves from the ground down in subway construction. It began to be applied in construction projects in the late 1950s, and is now widely used in the construction of Kunming subway

the grooved fuselage wears a green coat and steps on armored tracks. In front of the slender neck is an exaggerated front jaw. When it opens, it is easy to remind people of Tyrannosaurus Rex in Jurassic Park. As the slot machine swings its big mouth, when it is free to come and go on the subway construction site, other construction "King Kong" must make way for it

the grooving machine is a guy with a big appetite. In addition to the particularly hard rocks that can't be bitten, such as clods, sand, small stones, etc., you can eat them all, and you can especially eat them. It's no problem to eat dozens of cubic meters of soil a day. Because it prefers to eat "soft rice", (3) in order to maintain its good appetite, the construction personnel who pour concrete with a strength grade of not less than C20 in the pit will occasionally make some mud or the like to appetize it before the "dinner". This King Kong, who likes to eat "soft rice", is the right-hand assistant of workers. Almost every construction site has to keep 1-2 in captivity

2 excavator refitting drilling rig:

King Kong who dares to touch the "hard bone"

ruggedness: four-star

energy level: four-star

excavator is a excavator, and drilling rig is a drilling rig. What skill will you have if you combine the two things? In subway construction equipment, these machines, which can dig, break and drill, are full of wildness and are important killers of rocks

after refitting, each excavator looks different. L the whole system adopts digital design because the rocks they need to deal with are also different, which are mainly divided into two categories:

hydraulic drilling rigs are applicable to hard rock, medium hard rock and soft rock. It is widely used in the drilling process of marble, granite, metal mines, coal mines and non-metallic mines. In the subway project, it breaks hard rocks, and then the grooving machine that likes to eat "soft rice" pulls these crushed things out of the ground

the second is to refit the down-hole drill of the excavator into a rotary impact cutting down-hole drill. It can rotate or impact, and can also deal with all kinds of rocks. In case of soft rock, its rotating head will directly crush the rock, and it doesn't matter in case of hard rock. With the help of an air compressor, the hard rock will also be crushed by it through rotation and impact cutting. What is more rare is that this "King Kong" consumes less energy than ordinary drilling rigs, and moves quickly. It can fight when it is called
